<controlaccess> Controlled Access Headings

<controlaccess> is a wrapper element used to designate key access points for described materials. It enables authority-controlled searching across finding aids. It may be used at multiple levels within a finding aid. Higher-level <controlaccess> elements should encode access points which are relevant to larger portions of the collection, whereas lower-level ones may specify access points which only apply to a file or item.

Although names and terms from locally-controlled vocabularies are permissible, the <controlaccess> access point child elements (<corpname>, <famname>, <function>, <genreform>, <geogname>, <occupation>, <persname>, <subject>, and <title>) should come from national or international vocabularies whenever they are available to enable searches in information systems that include multiple finding aids, or finding aids and bibliographic records from many institutions. <name> may be used when the type of name or full name is uncertain.

The child elements mentioned in the previous paragraph all have @source attributes, which should be used to specify the source of the heading (such as source=”lcsh”). Their @rules attribute may be used to specify the descriptive rules which were used to formulate the heading (such as rules=”AACR2″). @relator may be used to specify the heading’s role in the collection—creator, subject, etc.
